1.2 (20 Marks) A beam of rectangular cross section (width b and height h) supports a uniformly distributed load along its entire length L. The allowable stresses in bending and shear are all and Tallow, respectively. a) If the beam is simply supported, what is the span length Lo below which the shear stress governs the allowable load and above which the bending stress governs? b) If the beam is supported as a cantilever, what is the length Lo below...
A rectangular cross section at a location along a beam in bending is
(a). A rectangular cross section at a location along a beam in bending is acted upon by a bending moment and a shear force. The cross section is \(120 \mathrm{~mm}\) wide, \(300 \mathrm{~mm}\) deep and is orientated such that it is in bending about its major axis of bending. The magnitudes of the bending moment and shear force are \(315 \mathrm{kNm}\) and \(240 \mathrm{kN}\) respectively. Determine the maximum bending and shear stresses on the cross section. Plot the bending and...

A timber [E = 1,800 ksi] beam is loaded and supported
as shown. The cross section of the timber beam is b = 4
in. wide and h = 7 in. deep. The beam is supported at
B by a 0.875-in.-diameter aluminum [E = 10,500
ksi] rod, which has no load before the distributed load is applied
to the beam. After a distributed load of w = 610 lb/ft is
applied to the beam, determine
(a) the force carried by...

A rectangular beam having b=16 in and d=26 in spans 28 ft face
to face of simple supports. It is reinforced for flexure with 6#11
bars that continue uninterrupted to the ends of the span. It is to
carry service dead load 2.0 kips/ft (including self weight) and
service live load 3.6 kips/ft, both uniformly distributed along the
span. Design the shear reinforcement using vertical U stirrups.
Economize the spacing of stirrups in appropriate number of bands.
Material strengths are...

305 lb/ft. The allowable bending stress of the wood is 1.30 ksi. If
the aspect ratio of the solid rectangular wood beam is specified as
h/b = 1.75, calculate the minimum width
b that can be used for the beam.
